In 2023, Fernan developed pubalgia due to a lack of training from previous surgeries in 2022 and 2023. He was hospitalised in late 2022 with an abscess in his larynx, leading to a tonsillectomy in early 2023. Complications resulted in internal bleeding, requiring a blood transfusion. He has also faced back injuries during his career.
Fernan's parents have been a significant influence on his life. He admires US basketball player Michael Jordan, Spanish tennis player Rafael Nadal, Serbian tennis player Novak Djokovic, Argentinian footballer Diego Maradona, and Japanese wheelchair tennis player Shingo Kunieda. His personal philosophy is "Fail harder, fail better."
He was Argentina's flag bearer at the opening ceremonies of the 2016 Paralympic Games in Rio de Janeiro and the 2019 Parapan American Games in Lima, Peru. In 2018, his biography 'Hambre de Lobo' [Hunger of the Wolf] was published, written by Sebastian Torok with a prologue by Rafael Nadal.
Fernan is married to Florencia Tagliaferro. He enjoys watching films and playing board games in his free time. He speaks both English and Spanish fluently. His personal coach is Jonathan Abadie from Argentina.
Looking ahead, Fernan aims to win a medal at the 2024 Paralympic Games in Paris. His rigorous training regimen and determination reflect his commitment to achieving this goal.
